2. Perforations of the wrong gauge applied: Several values of the 1917-19 perf 11 issues of the Washington-Franklins and the first issue of the 1922 regular series are known with all or most of the top or bottom row of perforations gauging 10. This was due to an improper repair to the perforating equipment. The stamps are rarities, but can be found in general collections. Values are in the $1000-and-up range. Expertization is essential.
Type 2: The 10x12 perforation of this Scott 423D was created as equipment was being modified to perforate at gauge 10 from gauge 12. Such varieties exist on the 1¢, 2¢ and 5¢ values of this issue.
